SPECIFLLCATIQN forming part of Letters Patent No. 713,074, dated November 11, 1902. Application ined August 16,1901. senato. 72.305. (Numan.)

To ctZZ whom, t Wtcty concern:

Beit known that I, JOHN W. DENMEAD, a citizen of the United States,residing at Akron, in the county of Summit and State of Ohio, have invented a certain new and useful Improvementin Box-Making Machines,of which the following is a specification.

My invention has relation to improvements in machines for making paper boxes, and has especial relation to the production of a machine for scoring, folding, pasting, and rolling a previously-cut blank in such a manner that the resulting product will be a flattened collapsed box capable of afterward being opened and with its ends in condition for ready folding.

The object of my invention is to produce a machine which shall be able to produceabox embodying the before -mentioned features and one in which all operations are performed entirely automatically.

To the aforesaid object my invention consists in the peculiar and novel construction, arrangement, and combination ofthe various parts hereinafter described and then specifically claimed, reference' being had to the accompanying drawings, forming a part of this specification.

In the accompanying drawings, in vwhich similar reference characters indicate like` parts in the different figures, Figure 1 is a plan of my improvedmaerhine; Fig. 2, an end elevation looking from theleftof Fig. l Fig. 3, a side elevation of part of Fig. 1; Fig. 4, a side elevation of the balance of the machine not shown in Fig. 3 on account of lack of space; Fig. 5, a section at the line :I: of Fig. 1; Fig. 6, a section at the line fg of Fig. 3; Fig. 7, an enlarged detail of the main cross-head; Fig. 8, a section at the line .e ,e of Fig. 7; Fig. 9, a detail of the scoring-roller arm; Fig. 10, adetail of the folding mechanism; Figs. 11, 12, and 13 and 14, details of the paper blank with the various scoring-marks, method of folding, dec.; Figs. 15 and 16, views of the complete box. Fig. 17 is a perspective View of a portion of my machine.

In the drawings, 1 is an elongated frame open in the center and supported upon pairs of legs 2 and 3. Projecting from the righthand side of the frame-1, Figs. 2 and 6, is a horizontal integral shelf 4, upon which are bolted two upright housings 5 and 6, having projecting integral parallel arms which support ashelf or table 7, having a downwardinclined part situated between the housings 5 and 6.

Mounted in vertically-adjustable boxes in the housings 5 and 6 is a shaft 8, provided at its outer end with aspur-gear 9, which meshes in a pinion 10 on a parallel shaft 11, mounted in the housings 5 and 6. On the shaft 8 are two semidisks 12, mounted on hubs and fastened tight on the shaft. The shaft 11 is enlarged between the housings 5 and 6 into a roller having at intervals deep notches cut therein'. The semidisks 12 and the main surface of the roller are arranged to pass in very close proximity to each other. Mounted in the housings 5 and 6 and in front of the vshaft 11 is a shaft 13, bearing a number of collars, two of which bear projecting extended tangential arms 14, having sharply-upturned ends which rest in the grooves in the roller on the shaft 11. These hooked ends normally are held downin the groovesin the roller by a spring 15, attached to a pin on a collaron shaft13. In order to raise the hooked ends above the periphery of the roller on shaft 11, an arm 16, provided with a friction-roller, is placed on the end of shaft 13 and arranged `to encounter a concentric strip 103 on the inner side of the gear 9. This strip 103 extends only substantially half around the gear 9 and is so placed as to rock the arm 16 on shaft 13 and cause the hooked ends 14 to rock upward and project above the periphery of the roll on shaft 11. Also mounted in the housings 5 and\ 6 is a shaft 17, bearing a desired number of scoring-rollers 18, which run in close proximity with similar rolls 19 on a shaft 20, which are mounted on vertically-movable slides 21.

The slight space between the scoring-rolls 19 and 18 is in the same horizontal plane as the similar space between the semidisks 12 and the roller onv the shaft 11, so that an article, as a sheet of cardboard, passingbetween the latter two will also be engaged by the scoring-rolls 19 and 18. The shaft '11 is provided on its left end, Fig. 3, with a spur-gear 22, which meshes into an idler 23, meshing into a gear 24 on the shaft 17, bearing the lower scoring-rolls. This last gear 24 meshes with the gear 25 on the upper scoring-roll IOC shaft 20, and the direction of revolution. of the shaft is indicated by arrows in Fig. 2. Upon the feeding-table 7 is a guide 26, the object of whichisto direct the supplyofblanks to the first set of rolls.

Across and between the housings 5 and 6 (see Figs. 1, 2, 3, and 4) is a bar 67, to which are secured, by means of thumb-nuts or otherwise, two downwardly-pressing springs 101, bearing upon the upturned face of the hooked ends 14. The ends of these downwardlypressing springs are rounded and are used to direct with more certainty the travel of the advancing blank from the top of the roller on shaft 11 to the union or space between the first pair of scoring-rolls 18 and 19 and prevent the tilting or any upward motion of the blank while awaiting to be acted upon by the semidisks 12.

Attached to the frame are two upright brackets 27 and 28, supporting a table-top 29. These brackets 27 and 28 are mounted on the main frame 1 and consist of asingle bar bent upward lo support the table-top 29 and then downward and having both ends bolted to the frame. This table-top 29 consists of a thin sheet of metal extending from near the junction or near the central line between shafts 20 and 17 and has mounted on its upper surface a bracket 30, which sustains a horizontal shaft 31, mounted upon which is an arm 32, bearing a shaft on which is mounted a wheel 33, having on its outer periphery a coating or band of rubber and adapted to nearly touch the table-surface 29. Between the wheel 33 and the arm 32 is a pulley, on which runs a belt 34, which also passes over a pulley mounted on shaft 20 and through which motion is communicated to the wheel 33.

The operation of the device thus far described is as follows: Blanks cut in the shape indicated in Fig. 11 are passed over the tabletop 7,substantially between the roller on shaft 11, and are engaged by semidisks 12. They are by the motion of these two passed forward between the scoring-rolls 18 and 19, which indents upon their surface the lines indicated by dotted lines in Fig. 11, and through the scoring-rolls they pass out upon the table-top 29 until they reach an abutment-plate 35, placed on the table adjustably and shown in Figs. 1 and 2. In order to secure the perfect and even meeting of the head of the incoming blank against this plate and to provide for its meeting it squarely, the roller 33, covered on its outer edge by rubber, is constantly revolved in the same direction as the shaft 17, the constant aim of which is to force the blank against the abu tment-plate iirmly and squarely. In placing these blanks for their scoring, before described, they are slid by hand over the rolleron shaft 11 until they encounter the two hooked ends 14, which trues them evenly with the side guide 26, and are held against further forward motion by the roller-arm 16 being in contact with the coucentric strip on gear 9; but as one end of the semidisks 12 approach the rolleron shaft 11 the roller on arm 16 runs over the end ofthe strip 103, and the springs 15 draw down the hooked ends 14,permitting the semidisks 12 to squeeze the blank between them and the roller ends of the shafts 18 and 19, by which it receives the creases before noted and from which it emerges out upon the table 29 nntilit encounters the rubber-covered wheel 33,which brings it squarely against the abutment-plate 35 ready for the next operation. Upon the table 29 is a slightly-raised plate 36 adjacent to the rubber-covered wheel 33, and this plate consists ot' a thin adjustable sheet 0f metal, smoothed on four sides, over which the incoming blank passes, and its object is to slightly raise the blank from the table-top 29 in order to more fully insure frictional engagement with the wheel 33. The shaft 11 contains outside of the pinion 10 a universaljoint 37 and receives power by being provided at its free end with a beveled pinion 38 and is supported by a bracket 39, bolted to the main frame of the machine. This pinion 38 is rotated by meshing with a beveled gear 40, mounted on a main shaft 41, supported in suitable brackets on the u nder side of the main frame of the machine. This shaft 41 is driven by a pulley 42 from any convenient source of power. The shaft 41 also bears a loose pulley 43, upon which the belt may be shifted at times when it is not desired to operate the machine. A belt-shift 44, properly jonrnaled and secured in the machine, is used to move this belt from the tight pulley to the loose and back again. The rotation of the main shaft 41 in turning rotates the beveled gear 40, the pinion 38, and the shaft 11 and through the beveled pinion 10, the main gear 9, and the semidisks 12. The rotation of the shaft 11 through the gear 22 operates the idler 23, the gears 24 and 25, which operate the scoring-rolls 18 and 19. The rotation of the shafts 17 and 20 operate the belt 34 and the rubber-covered Lwheel 33.

The method of producing the pair of vertical score-marks on the blank (indicated by dotted lines in Fig. 11) having been described, the process of making the cross-scoring shown by dotted lines in Fig. 12 follows. Mounted to slide on the parallel sides of the frame lis a cross-head 45, the motion of which is reciprocating along the frame, the motive power for which is furnished by means of a connecting-rod 46, uniting a pair of depending arms, 47, bearing a shaft-journal for the connecting-rod 46, with a pair of revolving cranks 108 on the main driving-shaft 41. This crosshead has depending fianges to furnish guides to bear against the sides of the frame 1 and steady the movements of the cross-head 45. Upon the upper face of the cross-head are a number of strips 106, running longitudinally thereof and transversely adjustable with relation to one another by means of screws passing through them and engaging nuts in shal- [OCI IIO

low transverse grooves of the cross-head. (See Figs. 5 and 7.) The upper faces of certain of the strips 106 have slightly-raised ridges (Indicated by lines in Fig. 7.) Mounted- 105. on the sides of the frame 1 are upright brackets 48, the office of which is to hold an irrevoluble cross-shaft 51, from which depend a desired number, as four, of arms, in the lower ends of which are pivoted score-wheels 50.l These wheels 50 are grooved to receive the' raised ridges 105 on the longitudinal strips 106 on the cross-head. These arms 49 (shown eularged in Fig. 9) consist of split heads clamped by bolts about the shaft 5l and split at their free ends and to the lower lesser halves of which are journ/aled the scoring -rolls 50, whose Vertical positions are adjusted by'setscrews 107, meshingin the upper firmerhalves of the arms '49.

The scoring-wheels 50 are intended to prof duce the transverse scores upon the blank (indicated in Fig. 12) by transverse dotted lines, and it is evident' from the preceding that-if. means are provided for the blank to befed forward upon the table 29 and to travell with thev cross-head the blank going at this time in a sidewise direction will be scored upon the lines indicated in Fig. 12 by dotted lines by means of the before-mentioned scoring-.rolls and the raised strips 106 upon the cross-head 45. g Y

In order to provide means to cause the blank after leaving the iirst pair of scoring-rolls tov move with the cross-head, I have provided the followingdescribed nippers to seize the blank and hold it firmly upon the raised ridges' of the cross-head and cause it to travel there-A with to a determinate distance.

I nthe front portion of the c rosshead arel two projecting arms bearing journal-bearings yin which is mounted a shaft 52, capable of rotation. Upon this shaft is mounted a pair of arms 53, having at their outer tapered ends a corrugated surface and adapted when' swung in one direction to press tightly upon the adjacent corrugated ends vof two of thev longitudinal ridges on the cross-head. Upon this shaft 52 is also mounted a small spurgear 54, arranged to mesh in rack-cut teeth on the upper surface of a bar 55, slidably at-y tached to the under side ofthe cross-head by'l Depending from this bar 55 means of bolts. is a stud 56, arranged to inclose a longitudinal rod 57, extending substantiallythe entire distance of the frame and fastened thereto.`

is provided at one end with a curved strapl 62 and at the other end nearly meets anupright downwardly-turned strap or bracket 63. f The bar.61 is separated from and mounted on one side of the main frame 1 and in such a position that when-the pin on the crank-arm 60 is rocked upward will engage it and prevent its upward movement. The operation of this last-named device is as follows: The blank after passing tl1roughthe lirst pair of scoringrollers and being pressed firmly and squarely against the abutmentplate 35 by the roller 33 vslightly overhangs the edge of the plate 29 on one side. The cross-head bearing longitudinal strips 106 is arranged to pass immediately under the plate 29, and the nippers 53 are then swung around by the lmechanism before described and grasp the paper between their corru gated ends and the corrugated ends of the strips on the cross-head and draw the blank sidewise along with the cross-head in its return stroke until by the before-mentioned mechanism the nippers are swung in an opposite direction and release the blank. The manner in which the nippers are caused to swingin one direction and then in another is as follows: The slotted bar 55 is permitted a slight longitudinal motion by reason of the slot in it, and any motion communicated to this rack by means ot the bar will cause a partial rotation of the small gear 54 and the shaft 52 in the cross-head, together with the nippers 53 mounted thereon. Now if thel cross-head moves in the direction of the main driving-shaft 4l the depending stud 5.6 will encounter the coiled springn58, which will press the stud 56, together with the slotted bar 55, in an opposite direction and tend to rotate the nippers in a direction to prevent their pressing upon the corrugated portions of the strips 106 on the crosshead, and consequently they would not press thereon and seize the paper or blank as desired were it not for the fact thatthe pin on the crank-'end of the shaft 52 is prevented from swinging around by reason of the bar 6l. As the crosshead nears the end of its stroke the pin will pass from under the bar 6l into the space (see Fig. 5) between the bar 6l and the strap 62, which will permit it to rise and swing upward, and as the cross-head returns Yon its stroke the pin will pass down under the bar G1 in-an opposite direction and slide on the under side of the bar 61 until at the completion of the stroke of the cross-head the pin on the crank 60 will pass from under the bar 6l and make a'partial rotation and be again drawn downward, following the center ofthe shaft 52 and force the nippers down upon the corrugated portions of the longitudinal strips 106 ofthe crosshead, so it will be seen that as the cross-head` moves in the direction of the 4main drivin-gshaft 4l the nippers 53 will beheld down upon any object-as, for instance, the blankin this case-and retain it until the pin has passed from under the bar 6l, which will permit'the partial rotation of the pin,and with it the nip-v pers, thereby releasing them from contacter engagementl with the blank, and in each.l mo- XOO IIO

tion of the cross-head in the opposite direction the nippers will stand in the position in dicated in Fig. 7.

In order to assist the blank in its transit with the cross-head, it is found that additional means of support therefor are needed. To accomplish this, there is placed at the extreme end (left in Fig. 1) an upright horizontal bracket 64, upon which is adjustably mounted two longitudinal square bars 65, which pass under the table 29 and over the face of the cross-head between its longitudinal strips 106 and are supported at their other ends by a like bracket 66 at nearly the opposite end of the machine. These bars afford an additional support for the blank in its travel after leaving the table-top 29 and support it after passing through the operations performed on the cross-head. In order to press this blank down firmly between the longitudinal strips 106 on the cross-head and upon the two bars 65, I place across the space between the side bars of the main frame 1 a bridge 68, consisting of two strips, one above the other, bolted together and clamping between them downwardly-pressing springs 69, whose object and purpose are to press firmly down on a blank passing through the machine and carried on the cross-head to assist in retaining the blank thereon. The position of these springs 69 is immediately above the square rods 65 and on which they normally press in the absence of blanks in the machine. Immediately above the strips on the cross-head and whose constant tendency is to force downward the traveling blank upon the cross-head I also fasten adjustably, by means of a bolt or screw, two folding-blades 70 to the arms 49, bearing the scoring-rolls 50. (See Fig. 5.) These two folding-blades 70 are so situated longitudinally that they press upon the scores made by two of the scoringrolls 50, and their purpose is to form the inside folding-blades over which the ends of the blank are bent in making the boxes. As their position is substantially on the scores, very slight effort is necessary to raise the ends of the blank to fold them over. During the transit of the blank on the upper surface of the strips 106 on the cross-head 45 paste is applied to the blank in the following manner and is placed upon that portion of the blanks designated by the letter A in Figs. 12, 13, and 14 on its under surface.

The paste is indicated in Fig. 13 by a corrugated surface, and this end is the last portion of the blank to pass between the preliminary scoringrolls, and therefore lies upon the right side of the table-top 29 in Fig. 2 and the lower part of the table-top in Fig. 1. In Fig. 6 is shown glue-wheel 99, mounted in the frame 1 and revolving in a hollow space in said frame and operated by means of a sheave on its shaft actuated by a belt 104, running over a sheave 102 upon the lnain driving-shaft 41 of the machine. This glue-wheel is arranged to place glue on the right-hand end of the blank during its sidewise transit on the cross-head.

The mechanism for folding over the ends of the now scored and pasted blank is as follows: Mounted on both sides of the main frame are two upright brackets 71, from each of which extend like shafts 72, whose axes are in alinement, bearing at their inner end and firmly secured thereto plates 73. At the lower sides of these plates are hinged folders 74. These folders are provided on the sides which are adjacent to the plates 73 with hardened-steel surfaces or plates (not shown)4 for the mechanism, to be hereinafter described, to bear. The general outline of these folders 74 is that nearest described by saying that they resemble a fiattened cows horn, whose points when rocked down will be below the level and between the longitudinal strips 106 on the cross-head, and so placed as to encounter the front edge of the advancing blank outside of the folderblades 70. These folders 74 are normally held upward (see Fig. 10) by a coiled spring 75, surrounding a rod, and which spring passes through the plates 73 and engages the comparatively at surface of the folders 74. It will be borne in mind that normally the position of these folders is that shown by the right-hand folder in Fig. 10, and they stand nearly against the plates 73 and are held there by the springs 75. The mechanism which causes them to swing on their hinges and throw their outer or free ends upward consists of two curved plates 76, mounted on a transverse shaft 77, rotating in brackets 78 on the sides of the main frame of the machine. These curved plates consist of sheets of hardened steel in the shape of involute curves whose vertical inclination is toward the center of the machine from their larger portions to their tips and which as they are swung around enter the space between the plates 73 and the attened or straight portions of the folder 74, and as they continue their revolution they force the folders downward to substantially a right angle with the plates 73 and cause the horns or tapered points of the folders to rise. As the blank in its movement along the top of the machine encounters the folding-blades 74 74 while in the upright position, as shown at the right-hand side of Fig. 10, the blank being held at the crease by the inside folder-blades, these horns 74 as the blank moves along fold up the sides of the blank on the line of the crease or score. The folding-blades are then moved by the parts 76, just described,downward into the horizontal position and fold over the blank upon itself. The rotation of the shaft 77 is caused and induced by a sprocket-wheel 79, which is rotated by a sprocket-chain 80 running over a sprocket-wheel on the main driving-shaft 41 and closely adjacent to the driving-pulley 42 and geared to such a speed as to cause the rotation of the shaft 79 and the plate 76 to operate the folders accurately IIO IZO

and absolutely to meet each advancing blank as it travels with the cross-head. The folders 74 are arranged to raise their outer pointed ends one slightlyin advance of the other, so that the portion of the blank marked A may be folded down first, and the portion marked B will fold over and slightly overlap the portion A, the portion A, which is intended to be overlapped by the portion B of theblank, having been coated before this by a suitable quantity. of paste to cause ad. v hesion.

The folders 72 are caused to operate one after the other and not simultaneously by. reason of the fact that the curved. plates 76 are set on the shaft 77 one slightly in advance of the other, so that one of the curved plates 76 commences its engagement with its folders 74' slightly in advance of the other. At the time that the folders 74E conclude their operation the nippers 53 will have been released from contact and engagement with the blank, and in order to continue the now folded blank forward I place on the shaft 77 an arm 8l, bearing on its outer edges a concentric foot S2, containing an arc of a circle which said arm 81 would described. This foot makes a revolution with each revolution of the shaft 77 and is adapted to bear upon the upper surface of the blank between the supportingrods 65 and, in combination with mechanism to be described, to push forward the now already pasted blank into the com pressing-rollers following. Below the shaft 77 and parallel therewith and journaled in the main frame of the machine is a shaft 83, bearing a slightlyedepending arm 84, on which is mounted a frictional roller 85, adapted to run on a largewheel or pulley S6, mounted on the main driving-shaft 4l of the machine. Upon this pulleyor wheel S6 is a cam-ridge S7, so placed that duringa portion of the revolution of the wheel 86 the cam 87 will encounter the roller`85 and through the arm 86 cause a partial rotation of the shaft 83. This cam-ridge S7 extends only a portion of the circumference of the wheel 86. Also mounted on the shaft 83 is an arm 88, bearing a roller 89, whose position is such that when the cam-ridge S7 on the vwheel 86 raises the arm 84 the roller 89, before mentioned, will press against the concentric foot 82 on theI arm Sl closely and will serve as a support for the under side of the advancing blank during the pushing of the same, due to the rotation of the foot.

The roller 85 is held in constant engagement with the wheel 86 and'cam-ridge S7 by means of a depending arm 90, constantly held in one direction by a coiled spring 91, fastened to any desired or preferred place on the main frame. At this point it is desirable to retain the advancing and now pasted and folded blank rmly upon the supporting-bars 65, and to insure this I place a cross-bar 92 upon the upper. portions of the main frame l .and towhich I bolt or fasten by any suitable means two downwardly-acting fiat springs 93, v

whose tendency is to bear down upon the ilpper surfaces of the supporting-bars 65, and thesesprings have upturned ends and are arranged to ride over and press down upon the advancing blank. Beyond the shaft 83, just previously described, and immediately above one another are two pairs of corrugated rollers 94, mounted on shafts 95, journaled transversely in the main frame of the machine and as shown in Fig. l. YThese rollers are adapted to run immediately outsidevof the 4supporting-bars 65 and are intended to seize upon and feed forward the blank. Adjacent to these last-named rollers are three pairs of compressing-rollers 96, arranged in pairs iminediately above one another, whose office is to roll the advancing and pasted blank firmly to insure absolute cohesion between the parts. The rolls 96 and the rolls 94 are arranged and adapted to run with a uniform speed and each pairin a like direction. Thisis accomplished hy placing on the upper and nearer end in Fig. l of the shaft 95 a belt-pulley 97, which is driven by any convenient source of power and in the same direction as that of pulley 42. The shafts 95 and the shafts of the compressing-rolls 96 all bear gears on one end and by means of idlers 9S are caused to ro tate ina uniform direction, the top row of gears meshing into the gears on the lower rolls primarily and the idlers are placed between the lower sets of gears.

At the extreme right end of the machine in Fig. l I place a hopper or shelf (better illustrated, perhaps, in Fig. 4) upon which the finished products may fall.

.Itis believed ,that the operation of the machine is sufficiently clear from the description accompanying the operation of the parts of the machine.

When the box leaves the machine, it is in the shape shown in Fig. 14 and is readily opened by hand and the ends closed, presenting when in this condition the appearance shown in Figs. l5 and 16, which represent the box with one end opened and one closed.

What I claim, and desire to secure by Letters Patent, is-
